USB devices, CD drivers. Only standard VGA drivers are loaded.

Freezing is often associated with faulty or poor Video drivers. OTOH few
viruses or other malware run in Safe Mode, so, no, don't *assume* a driver.
But try reducing hardware acceleration in Display Properties | Settings |
Advanced | Performance. See if there's an updated driver for your Graphics
card (or on-board video is that's what you've got).

I'm trying to figure out why my pc doesn't freeze in safe mode. What
drivers are not loaded in safe mode? I can run spybot, adaware, scan disk
and defrag in safe mode without it freezing. Should I assume that some
driver is not working right when I'm not in safe mode?

Thank you,
Pat
